Material Components Confirmation Dialog

Question

How can I implement the horizontal dividers or the elevation which can be seen on the Title and Buttons in the dialog box in the following image?

I have installed the material components library and used the dialog documentation as a guide.

The code is as follows:

MaterialAlertDialogBuilder materialAlertDialogBuilder = new MaterialAlertDialogBuilder(this.getActivity());

LayoutInflater inflater = ((Activity) context).getLayoutInflater();
View view = inflater.inflate(R.layout.dialog_settings, null);

setupView(view);


materialAlertDialogBuilder.setView(view);
materialAlertDialogBuilder.setTitle("Settings");

materialAlertDialogBuilder.setPositiveButton("OK", new DialogInterface.OnClickListener()
{
    @Override
    public void onClick(DialogInterface dialog, int which)
    {

    }
});

materialAlertDialogBuilder.setNegativeButton("CANCEL", new DialogInterface.OnClickListener()
{
    @Override
    public void onClick(DialogInterface dialog, int which)
    {

    }
});

materialAlertDialogBuilder.setCancelable(false);
materialAlertDialogBuilder.create();
materialAlertDialogBuilder.show();

The MaterialAlertDialogBuilder does not seem to have the ability to set this property.

Just use the standard MaterialAlertDialogBuilder.
It is the default behavior if you have the title panel, the button panel and a content that requires a scrollable view.

For example:

    CharSequence[] choices = {"Choice1", "Choice2", "Choice3", "Choice1", "Choice2", "Choice3","Choice1", "Choice2", "Choice3","Choice1", "Choice2", "Choice3","Choice1", "Choice2", "Choice3","Choice1", "Choice2", "Choice3"};
    boolean[] choicesInitial = {false, true, false, false, true, false,false, true, false,false, true, false, false, true, false,false, true, false};

    new MaterialAlertDialogBuilder(MainActivity.this)
        .setTitle("Title")
        .setMultiChoiceItems(choices, choicesInitial, null)
        .setPositiveButton("ok", null)
        .setNegativeButton("Cancel", null)
        .show();

Using a long message, with the title and buttons you can obtain:

new MaterialAlertDialogBuilder(AlertDialogActivity.this)
            .setTitle("Title")
            .setMessage(multiLineMessage.toString())
            .setPositiveButton("ok", null)
            .setNegativeButton("Cancel", null)
            .show();
